your welcome. Well for all your questions i have one answer. Run a tcl
script file that generates a trace file . in that file, you will have all
the information as far as my knowledge is soncerned about originator of the
RREQ packet. so there is no need for a counter. The node id descibes
whether ot not its the originator of the packet or not. for the malicious
node , as i said earlier , set a frequency of sending packets bu defining a
max limit . Once all other nodes note that they are receving unnecessarily
no of packets either discard or drop these packets by identifying the node
id of such nodes .
